* `skip=20`: because you set it in the URL
* `limit=10`: because that was the default value

## Optional parameters

The same way, you can declare optional query parameters, by setting their default to `None`:

```Python hl_lines="7"

```

MinIO to get temporary credentials for MinIO API operations. MinIO STS API uses [JSON Web Key Set Endpoint](https://docs.wso2.com/display/IS541/JSON+Web+Key+Set+Endpoint) to validate if JWT is valid and is properly signed.

**We recommend setting `policy` as a custom claim for the JWT service provider follow [here](https://docs.wso2.com/display/IS550/Configuring+Claims+for+a+Service+Provider) and [here](https://docs.wso2.com/display/IS550/Handling+Custom+Claims+with+the+JWT+Bearer+Grant+Type)...

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.

## Optional File Upload

You can make a file optional by using standard type annotations and setting a default value of `None`:

| policy     | _string_ or _[]string_ or _comma_separated_value_ | Canned policy name to be applied for STS credentials. (Mandatory) - This can be configured to any desired value such as `roles` or `groups` by setting the environment variable `MINIO_IDENTITY_OPENID_CLAIM_NAME` |

## Get started

In this document we will explain in detail on how to configure all the prerequisites.

You could use these tools and ideas if you are setting up **your own deployment system** while taking care of the other deployment concepts yourself.

	etcdClient  *clientv3.Client
}

// EtcdOption - functional options pattern style
type EtcdOption func(*CoreDNS)

// DomainNames set a list of domain names used by this CoreDNS
// client setting, note this will fail if set to empty when
// constructor initializes.
func DomainNames(domainNames []string) EtcdOption {
	return func(args *CoreDNS) {
		args.domainNames = domainNames
	}
}

var (
	timeSentinel     = time.Unix(0, 0).UTC()
	timeSentinel1970 = time.Unix(0, 1).UTC() // 1970 used for special cases when xlmeta.version == 0
)

// Boot modTimes up to disk count, setting the value to time sentinel.
func bootModtimes(diskCount int) []time.Time {
	modTimes := make([]time.Time, diskCount)
	// Boots up all the modtimes.
	for i := range modTimes {
		modTimes[i] = timeSentinel
	}

NetworkPolicy spec](https://kubernetes.io/docs/tasks/administer-cluster/declare-network-policy#before-you-begin),
and set `networkPolicy.enabled` to `true`.

For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting
the DefaultDeny namespace annotation. Note: this will enforce policy for *all* pods in the namespace:
